Bug in radix_sort in SVN release #20

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago

Hello !

I'm trying to sort data using a radix sort, and I experience a bug, i.e.
the data are not always sorted.

On the opposite, when I use a merge sort, everytinhg is ok.

Moreover, when I use this code with the 1.0 release of thrust, the radix
sort seems to work.

You'll find enclosed a small code.

P.S. : I'm using a nvidia geforce 8800 with cuda2.3 under linux.

Thanks for the report!

I suspect this is due to a bug in scan() that is known to appear on G80-based 
devices
(like the GeForce 8800).  Anyway, we'll have a fix for you soon.
